ADASH DDS tutorial 14 - Threshold parameter
What exactly the threshold value is and why we use it in DDS software?
adash.com/software-vibration-analysis/digital-diagnostics-system
The threshold is a parameter, which is used in online systems.
The threshold idea came from vibration measured on hydroelectric turbines. Such machines are not running continuously. The turbines are run and stopped several times every day. And we want to save just running values.
When such intermittent machine is turned off there remains noise values, which we don’t want to save. It means, when the values are lower than the threshold value, we do not save them.
When the measured value is above threshold, then the machine is running. When the measured value is bellow, then the machine is not running. To set the threshold correctly is important.
How to choose the threshold value? Threshold value has to be lower than normal machine vibrations and higher than noise value.
It means if normal machine vibration is 2 mm/s and noise value is 0.2 mm/s than the threshold value should be set for example to 0.5 mm/s.
Where you set this value in DDS? Open DDS software. Open your online database. Go through the tree to data cells level. Click on measurement data cell with right mouse button. Choose Properties. Go to online tab.
You can see saving section here. There is parameter named Min value threshold. This parameter stands for the threshold value. Click to the field next to Min value threshold name. Fill in your chosen threshold value. You can decide that this data cell threshold value will be set for the whole machine. All data cells on this machine are still measured but they do not save the data. Machine is considered as not running. Until this one data cell - marked as threshold data cell - measures values higher than set threshold. From that moment values are saved in all data cells according to data saving parameters set.
Once the threshold is set, it is important to start the measurement again or to press the continue button.
From now - values below the threshold will not be saved. Unless.
There is one exception. Adash threshold is smarter.
When value decreases below the threshold this first value is saved. Now you know that you are in not running vibration values. Next ones below threshold are not saved. Unless the values go up and get above the threshold. The last value before we get again above the threshold is saved also.
Keep in mind that threshold parameter should be used only for machines which are not running continuously. It is also important to choose proper value as a threshold value.
Now you know how to use the threshold parameter. Thank you for watching.

Combination of two vibration signals (sum of two signals)

Combination of two signals - what happens if there are two sources of vibrations in a machine? Let’s assume each source creates a signal with a single sine wave. We will cover four possibilities. First, let’s look at two waves of a similar frequency. One of them is a 25 Hz wave. A time signal measurement displays a sine wave. A spectrum measurement would show wave as a single peak at 25 Hz.

why are the amplitude units mm/s @ 5:23 it should be mm right?

1st & 2nd modal.
Thank you for this video series, appreciate them 👍🏻
Excellent! May I ask if I can split the adjustment weight on both sides of the suggested spot?
This is a great feature and highly applicable to lots of equipment and machinery in a wide range of manufacturing.

What is the name of the track in the background?

i wish we could access subtitles like a whole text🥲 can someone help me
Would placing the reflector and sensor in horizontal alignment provide a more accurate measurement?
Wau🤩👍

Hindi me video baniye
This is great, new to the whole concept but want to understand and learn. What a great place to start, low cost software, thank you very much. Cheers to you, good job on the video too.
Thanks a lot for making this video and animation too. but you should mentioned that all these descriptions are about single plane balancing! in dynamic or couple mode, the process is different. But it worth mentioning in your next videos :) especially by introducing coefficient parameters.
DO NOT run the fan with the hatch cover off! This will be a violation of safety protocol on EVERY plant site! You never know what is in that ductwork - product, welding slag, welding rods, etc. You don't want that coming out of the fan. If you are using “clamp on” weights they can and DO come off sometimes. Hatch only needs a couple of fasteners, but NEVER run a fan with the hatch cover off!!!
For serious analysis the “recorder” function is a must have. Many times in my career I have wished I had this feature. Well done!
que sensor es el recomendable ?
It depends on particular application / measured machine. But most common sensor used in vibration analysis nowadays is 100 mV/g acceleration sensor.
why we took 2048 samples?
Salam , I guess we took that number because The resolution of ADC is 11bits

hows that vector type graph is generated..can anyone tell?

Saludos cordiales amigo he visto un par de vídeos suyos y me parecen muy buenos. Ahora mi pregunta es las máquinas sometidas a análisis de vibración ya vienen con los puntos dónde deben hacerse los análisis? Si no es así entonces cuales serían los puntos dónde se deben realizar estos estudios. Gracias de antemano saludos desde Roma
Most of the machines will not have already prepared measurement points and you have to prepare them on your own. How to do that is described here: adash.com/vibration-analysis/how-should-start-predictive-maintenance-program/

thanks for the help Do you have info on frequencies and what they mean
This is very general question. There is endless types of machines and their applications in particular industries. Every machine or machinery set (e.g. motor with gearbox and pump) generates vibrations on specific frequencies according to their construction and other parameters such as speed, load etc. There are speed frequencies, gear mesh frequencies, bearing frequencies, drive belt frequencies to name a few. Therefore there is no general answer to your question.
Great video, cheers!
Sr cuál es el valor de vibration
That is really difficult question. You would need to be more specific please.
Where should all three same weight be added with rotation or against rotation?
Dont matter
Does not matter. But the direction of rotation can not be changed during balancing job.
muy bueno soy estudiante y me es enriquece el tema
Gracias Señor
THE WHOLE VIDEO WAS VERY INFORMATIVE. BUT GUYS DONT CLICK ON 8:53
Oops, sorry :-)
Hello sir Adash it is neccesary the weight, input the weight ,rotor mass?
Not necessary.

The relation between meter and millimeter is a constant value and it is defined as “One meter is equal to 1000 millimeters"
